Laurence 6555e774d9 Telescope review: all 23 active iTelescope systems
Adds TELESCOPES.md, a per-observatory review of every telescope on the
iTelescope.net network with a spec block and an assessment for each, a
'choosing a telescope' use-case table, and general observations (CCD to CMOS
migration, Bin2 software limits, elevation limits, network-side calibration).

Data sourcing:
- data/itelescope-telescopes.csv is a verbatim CSV export of iTelescope's
  maintained specs Google Sheet (24 rows: 23 active scopes + T74 placeholder).
- The support article (Freshdesk 247371) supplied observatory groupings and
  minimum elevation limits; it still lists T9/T19/T31/T69 which the sheet has
  dropped - the review follows the sheet and records the discrepancy.
- go.itelescope.net is an authenticated app shell; nothing was scraped from it.

Also fills in the remaining state/ files: TODO (pending: T74 specs, retired
scope reconciliation, periodic sheet refresh), DECISIONS (source-of-truth
choice, single-document structure, no launchpad scraping), NOTES (refresh
command, CSV quirks), ARCHITECTURE (repo layout), and README.

Decisions

A dated, append only log of decisions and their rationale. Newest at the top. Never rewrite past entries; if a decision is reversed, add a new entry that says so.

2026-07-17: follow the Google Sheet, not the support article

The support article (https://support.itelescope.net/support/solutions/articles/247371) and the maintained Google Sheet (https://docs.google.com/spreadsheets/d/1jZWkkjewOuyNC9YzQ8y2d0pO1e4T7EBeysmQMPBVSOk/) disagree: the article lists T9, T19, T31, T69, which the sheet omits; the sheet has T25, T26, T59, T71-T75, T80, which the article lacks. The article itself points to the sheet as the current source, so the review follows the sheet and notes the discrepancy. The sheet CSV export is snapshotted in data/ so the review's numbers remain reproducible even if the sheet changes.

2026-07-17: single review document, not per-telescope files

23 active scopes each need only a spec block and a short assessment; one TELESCOPES.md grouped by observatory reads better and is easier to keep current than 23 stub files. Revisit if per-scope content grows (photos, session logs).

2026-07-17: no launchpad scraping

https://go.itelescope.net/ is an authenticated app shell with no public data. All content comes from public support pages and the public sheet; nothing in this repo requires iTelescope credentials.

Per-telescope detail pages, if ever needed: support.itelescope.net/support/solutions/articles/231901-231920 (older scopes), 245471 (T68), 251171 (T70), 251556 (T69), 251589 (T19).
